Chapter 3: Money, or the Circulation of Commodities

Page 217

In the velocity of circulation ... there appears the fluid unity of the antithetical and complementary phases, i.e. the transformation of the commodities from the form of utility into the form of value and their re-transformation in the reverse direction, or the two processes of sale and purchase. Inversely, when the circulation of money slows down, the two processes become separated, they assert their independence and mutual antagonism; stagnation occurs in the changes of form, and hence in the metabolic process.
